Effects of increased stocking density and supplemental feeding on the production of milkfish fingerlings

Experiments were conducted in twelve 144 sq. m. brackishwater ponds at Leganes Research Station, SEAFDEC, to determine the effect of increased stocking density and supplemental feeding on milkfish fingerling production. Two stocking densities (50 and 75 fry/sq. m.) with and without supplemental feeding with rice bran and a formulated diet were tested in a completely randomized design with three replicates. Results showed that increased stocking density from 50 fry/ sq. m. to 75 fry/sq. m. fed with rice bran gave a mean survival rate of 71.50%. Growth, measured in terms of weight and length, was not significantly different between treatments. Profitability of increased stocking density and supplemental feeding are discussed
